I was playing Pokemon go and I came across a Chikorita.I never caught one and it was a starter in gen 2. I tried to catch it but I couldn't. I WASTED 10 POKEBALLS ON THE THING!!! Please give me a tip or 2 on how to catch it.
You can use Razz Berries on wild Pokémon to up their catch rate. It only works for one turn though, so stock up on them. That's the only way to increase catch rate that I know of, aside from using Great/Ultra Balls if you're at a high enough level.
